Study Notes
Respiration
- Process by which cells generate energy from glucose
- Involves the breakdown of glucose to produce ATP
- Occurs in the mitochondria
- There are two types:
- Aerobic respiration (oxygen present): produces 36-38 ATP molecules
- Anaerobic respiration (oxygen absent): produces 2 ATP molecules
- Importance: provides energy for cellular activities
Excretion
- Process by which waste products are removed from the body
- Types of excretory organs:
- Kidneys: filter waste from blood, produce urine
- Liver: filters waste from blood, produces bile
- Lungs: remove carbon dioxide
- Skin: removes water and salts through sweating
- Importance: maintains homeostasis, prevents toxin buildup
Circulation
- Process by which blood is circulated throughout the body
- Components:
- Heart: pumps blood throughout the body
- Arteries: carry oxygenated blood away from the heart
- Veins: carry deoxygenated blood back to the heart
- Blood vessels: allow exchange of oxygen and nutrients with cells
- Importance: delivers oxygen and nutrients to cells, removes waste products
Photosynthesis
- Process by which plants produce glucose from sunlight
- Occurs in chloroplasts
- Equation: 6CO2 + 6H2O + light energy → C6H12O6 (glucose) + 6O2
- Importance: produces oxygen, provides energy for plants
Nutrition
- Process by which organisms obtain energy and nutrients
- Types:
- Autotrophic: produce own food through photosynthesis
- Heterotrophic: obtain food by consuming other organisms
- Importance: provides energy and building blocks for growth and maintenance
Transportation
- Process by which materials are moved within an organism
- Types:
- Passive transport: movement of materials without energy input (diffusion, osmosis)
- Active transport: movement of materials against concentration gradient using energy
- Importance: maintains homeostasis, allows for proper functioning of cells and organs
Respiration
- Generates energy from glucose for cells
- Breaks down glucose to produce ATP (energy currency)
- Takes place in mitochondria, occurs in two types:
- Aerobic respiration: 36-38 ATP, oxygen present
- Anaerobic respiration: 2 ATP, oxygen absent
Excretion
- Removes waste products from the body
- Excretory organs:
- Kidneys: filter blood, produce urine
- Liver: filter blood, produce bile
- Lungs: remove carbon dioxide
- Skin: remove water, salts through sweating
- Maintains homeostasis, prevents toxin buildup
Circulation
- Circulates blood throughout the body
- Components:
- Heart: pumps blood
- Arteries: carry oxygenated blood
- Veins: carry deoxygenated blood
- Blood vessels: allow oxygen, nutrient exchange with cells
- Delivers oxygen, nutrients to cells, removes waste products
Photosynthesis
- Produces glucose from sunlight in chloroplasts
- Equation: 6CO2 + 6H2O + light energy → C6H12O6 (glucose) + 6O2
- Produces oxygen, provides energy for plants
Nutrition
- Obtains energy, nutrients for organisms
- Types:
- Autotrophic: produces own food through photosynthesis
- Heterotrophic: obtains food by consuming other organisms
- Provides energy, building blocks for growth, maintenance
Transportation
- Moves materials within an organism
- Types:
- Passive transport: movement without energy input (diffusion, osmosis)
- Active transport: movement against concentration gradient using energy
- Maintains homeostasis, allows proper cell, organ function
